Setting up private networking in AWS environments

The topics in this section describe how to enable private subnets in Cloudera Data Warehouse (CDW) on AWS.

Required role: DWAdmin

In AWS, a public subnet is connected to an internet gateway which can send and receive traffic directly to and from the internet. Private subnets send outbound traffic from nodes to the internet by using a network address translation (NAT) gateway, and then forwards the traffic to an internet gateway. Private subnets receive no direct inbound connections from the internet. This provides private network connectivity for workload endpoints in CDW service.
